To all whom itmay concern. I of thefbattery, and therefore with one pole Be it lmown that I, Wanna D. KAHN, a citizen of the United States, and a resident of the city, county and State of New York, have invented an lm rovement in Portable Electric Lights, of w 'ich the following is a specification.

My invention relates to a portable electric light operated from dry cells and sometimes referred to as a flash-light, which comprises a container, frequently made of metal, a reflector mounted within the container and cara lamp, a lens by which the reflector is usually retained in place, a dry battery and suitable switching mechanism.

My invention relates more particularly to improvements in the switching mechanism for this type of lamp and aims to produce a switching mechanism of simple and inexpensive construction, which is positively and easily operated is capable of easy repair and adjustment and is soarranged as to prevent metallic objects which may be in contact with various portions of the container. My invention is particularlfl applicable to flash-lights havmg a m c caseilbut it will beunderstnod that it may be app 'ed to flash-lights havin a case of fiber or other insulating materi y In the drawings;

located a lens 5 held in place by a screw-ca 6. Lens 5 bears against a reflector 7 whic is provided with a screw-threaded c lindrical portion within which is moun the lamp 8. 4 Located within the case is an ins'ulat' member 9 of, disk shape, having a cent screw-threaded aperture within vwhich the screw-threaded end of the reflector is secured, and a notch 10 at its periphery, the purpose of which will be hereafter explained. Attached to the under side of the insulating disk 9 is a metallic member 11, which, may be in the form of cup, or may take any other suitable shape perform the functions hereinafter described. Mounted warm D. m, 01' NEW YORK, N. Y., ABSIGIIOB '10 mos-r SALES 001mm, OI 1 within themetallic memberill is .a sprindg or any other suitable fastening 15. The insulating disk member 13 carries on it's under side a metallic member 16, which may beattached to the disk member 18 by means of a rivet 17, or any other suitable fadening. Metallic member 11.? is provideiliocvzlith a spring projection 18 aving. a pro 'on 19 idi ad'w be brouht into contact with the metallic member 11.

The construction is preferably such that the projection 23 fits into the depression opposite the projection.

'portable electric light, since all of t e exposed portions of the case are of the same polarity, and it is therefore possible to make a circuit through the battery only by operationof the switch mechanism.

While I have only described one form of my invention, it is obvious that it may be greatly varied without departing from its spirit, and I therefore do not intend to confine myself to the precise details shown and described.

What I claim is:

1. A portable electric light, comprising a member of insulating material, a reflector secured thereto, a metallic member secured to the member of insulating material and in contact with one pole of the lam a second insulating member, a spring mem er mounted thereon, and means for flexing the spring member into contact with the metallic member to close the circuit of the lamp.

2. A portable electric light, comprising a notched disk offinsulating material having an aperture, a reflector secured in said aperture, a metallic member mounted upon the disk, a bump mounted within the reflector and electrically connected to said metallic member, a second notched disk of insulatin material secured to said metallic member an a second metallic member secured to said second disk and having a projection adapted to be brought into contact with the first metallic member, and means, operable when the notches in the insulating disks are in alinement, for eflectin such contact.

3. A portable electric light, comprising a member of insulating material, a cup-shaped metallic member secured thereto, a lamp mounted Within said insulating member and contacting with said cup-shaped metallic member, a second insulating member secured to said cup-shaped metallic member and a second metallic member carried by said second insulating member and having a projection adapted to contact with the side of said cup-shaped metallic member.

4. A portable electric light, comprising a casing, an insulating member mounted within the casing and disposed transversely thereof, a metallic member carried by said insulating member and having a portion of its surone another, a lamp in contact with one of said contact members, a battery in contact with the other of said metallic contact members, and a contact controlling membermovable within the notches in said disks and adapted to move one of said metallic contact members into contact with the other.

6. A portable electric light, comprising an insulating member, a fixed metallic contact member carried thereby, a second metallic contact member, a second insulating member inter sed between said metallic contact mem ers, one of said metallic members being provided with aprojection adapted to be moved into contact with the other of said metallic contact members and being provided with a depression, and a switch controlli member provided with a projection adap to cooperate with the depression in said metallic switch controllin member to lock the switch controlling mem er in position.

7. A portable electric 1i ht, comprisin a disk ofmsulating materia provided with a threaded central aperture and a notch at its periphery, a second disk of insulatin material also having a notch at its perip cry, a metallic contact member mounted upon each of said disks, one of said metallic contact members being provided with a rojection eatending into the notches of hot of said disks and in pgoximit to the other metallic contact mem r, an a switch-controlling member adapted to cooperate with said proection to cause contact with said metallic contact members and adapted to be moved in said notches. I

8 A portable electric light, comprising a cylindrical case, a reflector mounted therein and in contact therewith, a disk of insulating material having a central aperture in threadfiector and in contact with said metallic contact member, a seco'nd disk of insulating material attached to said metallic contact member, a second metallic contact member carried by said second disk and having a pro- 'ection disposed longitudinally of the case,

at out of contact therewith, a battery connected to said second contact member and a. contact controlling member mounted within the case and adapted to be moved longi- 10 tudinally thereto to move the projection upon said second metallic contact member into contact with the first.

In testimony whereof, I have signed my name to this specification this 6th day of 15 August, 1917.
